NXP Semiconductors MPC8347ECVVAGDB

Overview

MPC8347ECVVAGDB from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 667 MHz, dual 10/100/1000-Mbps Ethernet controllers (TSECs), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2-compliant 32-bit/66-MHz interface, and hardware security engine with AES-128/192/256, DES/3DES, SHA-1/256, and RSA acceleration. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8347ECVVAGDB datasheet, MPC8347ECVVAGDB pinout, MPC8347ECVVAGDB application, or MPC8347ECVVAGDB equivalent, this page delivers verified technical context on its e300 core architecture, DDR timing constraints, TSEC RGMII/GMII compatibility, PCI host/agent mode behavior, and security engine crypto-channel allocation-critical for boot firmware design, memory subsystem layout, and cryptographic throughput planning.

Technical Context

The MPC8347ECVVAGDB implements a superscalar PowerPC e300 core with 32-KB instruction and 32-KB data L1 caches (lockable portions), dynamic power management, and software compatibility across Power Architecture families. Its DDR SDRAM controller supports programmable timing for DDR-1, ECC, page-mode operation (up to 16 open pages), and registered DIMM compatibility with 2.5-V SSTL2 I/O.

Dual TSECs comply with IEEE 802.3z/802.3ab/802.3ac standards, offering GMII/RGMII/TBI/RTBI physical layer support, 9.6-KB jumbo frames, RMON statistics, and 2-KB Tx/Rx FIFOs per channel. The security engine integrates four crypto-channels with dedicated execution units for AES, DES/3DES, SHA/MD5, ARC4, and RSA/DH/ECC-enabling concurrent IPSec/SSL/TLS offload without CPU intervention.

Key Specifications

Pinout & Package

The MPC8347ECVVAGDB is housed in a 676-pin TBGA (Thin Ball Grid Array) package with 1.0-mm ball pitch, optimized for high-density PCB layouts in networking equipment. Thermal pad on underside requires solder paste stencil design per JEDEC J-STD-020.

FAQ

What is the maximum DDR-1 data rate supported by the MPC8347ECVVAGDB?

The MPC8347ECVVAGDB supports DDR-1 SDRAM at up to 333 MHz in TBGA packages (e.g., MPC8347ECVVAGDB), delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6.2.2 of the Hardware Specifications (Rev. 11), Table 14, which specifies tMCK min = 6 ns (166 MHz DDR clock → 333 MT/s). The PBGA variant is limited to 266 MHz.

Does the MPC8347ECVVAGDB include hardware acceleration for TLS 1.2 handshake operations?

Yes, the MPC8347ECVVAGDB security engine includes dedicated execution units for RSA-2048, SHA-256, and AES-128/256 - all required for TLS 1.2 full handshake offload. Its four crypto-channels allow concurrent processing of asymmetric key exchange, symmetric key derivation, and record encryption, as documented in Section 1, "Overview", and Section 4, "Security Engine".

Can the MPC8347ECVVAGDB operate in PCI host mode while running the e300 core at 667 MHz?

Yes, the MPC8347ECVVAGDB supports simultaneous 667-MHz e300 core operation and PCI host mode. Section 13, "PCI", confirms PCI 2.2 compliance with 32-bit/66-MHz operation, and Table 4 shows 667-MHz core power dissipation data for both PBGA and TBGA packages under PCI host configuration - verifying functional coexistence.

What boot sources are natively supported by the MPC8347ECVVAGDB without external glue logic?

The MPC8347ECVVAGDB supports boot from I2C-1 EPROM (via embedded boot sequencer), parallel NOR flash (using Local Bus chip select), and serial SPI flash (via QUAD SPI interface). Section 1, "Overview", explicitly states "System initialization data optionally loaded from I2C-1 EPROM by boot sequencer embedded hardware", and Section 10 details Local Bus boot ROM configuration.

Is the MPC8347ECVVAGDB pin-compatible with the MPC8347ECVVAGD?

No, MPC8347ECVVAGDB and MPC8347ECVVAGD are not pin-compatible. The suffix "B" denotes a revised silicon revision (Rev. 3.0+) with corrected errata and updated electrical characteristics, requiring different DDR termination, reset timing, and PLL lock behavior - as noted in the document's "NOTE" on page 1 stating that Rev. 3.0+ parts require the MPC8347EA specification, not the base MPC8347E document.
